Abstract (en)
[origin: WO2013169174A1] The present invention concerns a plastic composition which is biodegradable, and which does not discharge contaminants during incineration or leave plastic fragments after decomposition. According to the invention the composition comprises: (i) 30-50 % by weight of a polyester which is biodegradable and/or decayable; (ii) 20-40 % by weight of starch from vegetable oil origin from corn, potatoes, and/or sunflower; (iii) 20-40 % by weight of a filler composition comprising dolomite and/or calcium carbonate, wherein the filler composition particles have a polished surface; and (iv) 1-5 % by weight of a binding agent comprising a resin ester of vegetable origin; wherein said polyester and said starch together form a bioplastic base composition and together comprise 55-79 % by weight of the total weight of said plastic composition. The present invention further concerns a method for preparing said plastic composition; a plastic film prepared of said plastic composition; and a waste bag prepared of said plastic film.
